This model is replaced in [1]} by the one where there is also a superfield \(T\)  which is a propagating superfield. Namely, the total Kähler and superpotential include the terms in eqs. (REF ) and (REF ) as well as \(\Delta K = - 3\ln (\rho +\bar{\rho })\)  and \(\Delta W= W_0 + A e^{ -a\rho }\) . They include some \(t\) -dependent factors of the form \(e^t\)  which at small \(t\)  are regular.
Most importantly, the superfield \(X\)  is not nilpotent anymore, since \(T\)  is a dynamical superfield.
